Abstract:: This paper addresses the network selection problem in Cogniive Radio Networks( CRNs) based onprice and 0oS requirements. Evolutionary game is used to model the nelwork seleetion problem in our paper tochoose the best aeeess nelwork for all users to maximize the revenue of the nelwork. Based on our model, ourwork took some 0oS requirements into aeeount and proposed an algorihm based on price and users’Qos re-quirements. Simulation results show that our algorithm can eapture the main faetors in network selection inCRNs and oblain a belter performance in a more realistie system.
